PLZ HELP 20 POINTS In the atom shown by the image answer the following two questions: How many electrons are in the outer ring? How many electrons would it react with to form a stable molecule?

There are 8 electrons in the outer ring, and has to react with 8 or fewer electrons to form a stable molecule.

Explanation:

The outer-most orbits of  silicon contains a maximum of eight (8) electrons. It requires 8 of fewer electrons to form a stable molecule.

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.
